(f. Sixth ventral segment triangularly emarginate. Genital armature 

 (fig. 1) : lateral lobes very long, slender, slightly sinuate, set with several 

 long, projecting hairs on the inner edge towards the apex; median lobe 

 drawn out into a long, slender point at the tip. 



Length 8-8i mm. ( (S 2 •) 



Hah. India, W. Almora (R. G. C). 



One pair, agreeing with Bernhauer's description of D. annandalei 

 in the rugosely punctured, mesially carinate base of the prothorax and 

 other particulars. His type, from Kurseong, was rather smaller (length 

 7 mm.). The peculiar sculpture of the prothorax, the shallower elytral 

 depressions, and the simply excavate, non-lobate fourth tarsal joint, 

 separate the insect before me from the very closely allied Z>. versicolor 

 Cameron. A detailed description of the Almora specimens is given, as 

 both authors have omitted to note the venti'al and tarsal characters. 



3. — Dianous inaeqiialis, n. sp. 



Nigro-cyaneous, the elytra and abdomen with a faint brassy suffusion, the 

 palpi and antennae black; moderately shining, finely pubescent, the prothorax 

 almost glabrous. Head broad, densely, very finely punctate, the intra-ocular 

 grooves deep ; eyes not very large ; antennae long. Prothorax narrov/, as long 

 as broad, the sides rounded anteriorly and sinuously converging towards the 

 base ; closely, coarsely, irregularly punctate, the punctures sometimes absent 

 along the centre posteriorly ; deepl}', obliquely sulcate, or angulato-excavate, 

 on each side behind the middle, and also obliquely grooved laterally before the 

 base, the submedian sulci more or less conflueut on the disc, and the raised 

 space in froiit of the latero-basal groove someAvhat nodose at its inner ex- 

 tremity. Elytra wider than tiie head, longer than broad; alutaceous, densely, 

 very finely punctate, strongly, irregularly plicate, the tumid portions of the 

 surface more or less sinuous and separated by rather broad, depressed spaces. 

 Abdomen closely, minutely punctate ; ventral segments 1-4 and G with a 

 polished glabrous space down the middle; anal brushes very long. Fourth 

 tarsal joint without lobes. 



(S . Sixth ventral segment triangularly emarginate. 



Length 7-7^ mm. 



Ilab. India, W. Almora (R. G. C. : vi.l918). 



Three males. This insect has the elytra still more uneven than 

 in Z>. versicolor Cameron, and the prothorax sculptured much as in 

 D. caeruleonotatus, the general coloration being darker — nigro-cyaneous 

 with a faint brassy suffusion, except on the head. 



4. — Dia7ious caeruleonotatus, n. sp. 



Brassy, brassy-green, or golden, the head, a transverse or arcuate patch on 

 the elytra just beyond the middle and a streak on the inflexed margin, the
